Greg, Maybe +8 but unsure on year two ring....might only be +7, can't see the second ring down by the broken off arrow fletch...maybe it is up at unbroken arrow fletches in the photo? Need a side view to be sure. Those monsters grow fast and usually die pretty young, many not making it naturally to 8 or 9, whether bighorn or thinhorn.

Agree need a better side photo to age, but when I zoom in red lines are most definitely growth rings, blue seemingly has to be one there somewhere, so 8.5 seems reasonable, maybe 9.5. Many of the growth rings are really long - must be some good nutrition and growth conditions!

I would find the best taxidermist at the Smithsonian Museum Of Natural History to mount him. Then I would build a new house to showcase it. Sorta like that big grizzly at the Cody Museum Of The West. Then I would get a bottle of Pappy Van Winkle and sit in my easy chair every night and fall asleep looking at it. Probably have a little slobber on my chin when I'd wake up. What a ram!
